TIMI Myocardial Perfusion Grade 1
Introduction
Overview
Overview
Dye slowly enters, but fails to exit the microvasculature. There is ground glass appearance (“blush”) or opacification of the myocardium in the distribution of the artery that fails to clear from the microvasculature, and dye staining is present on the next injection (approximately 30 seconds between injections).
Dye staining does not include arterial or venular stains. The TMPG should not be given a grade of 1 solely because either of the former are present, but only if myocardial or arteriole stains are present.
